If you have an air compresser you can get an automotive type tuch up gun ( mine is devibless) but harbor fright has on that will do, it will take a bit of learning on thinning the paint. you can get a realy nice finish with them.
But do to the smell and volatility, small quantity needed for model building I have switched to nelsons paints and a hvlp type gun little smell and eco frindly and with some practice you can get a finish as good as any paint, including automotive.
Hpe this helps
